Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 126,774,745, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 126,774,745 | |
| -1 | -126,774,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,774,745.
Example:
1 x 126,774,745 = 126,774,745
and
-1 x -126,774,745 = 126,774,745
Notice both answers equal 126,774,745
With that explanation out of the way, let's continue. Next, we take the number 126,774,745 and divide it by 2:
126,774,745 ÷ 2 = 63,387,372.5
If the quotient is a whole number, then 2 and 63,387,372.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 126,774,745 | |
| -1 | -126,774,745 |
Now, we try dividing 126,774,745 by 3:
126,774,745 ÷ 3 = 42,258,248.3333
If the quotient is a whole number, then 3 and 42,258,248.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 126,774,745 | |
| -1 | -126,774,745 |
Let's try dividing by 4:
126,774,745 ÷ 4 = 31,693,686.25
If the quotient is a whole number, then 4 and 31,693,686.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 126,774,745 | |
| -1 | 126,774,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 4,465 | 28,393 | 141,965 | 539,467 | 1,334,471 | 2,697,335 | 6,672,355 | 25,354,949 | 126,774,745 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -4,465 | -28,393 | -141,965 | -539,467 | -1,334,471 | -2,697,335 | -6,672,355 | -25,354,949 | -126,774,745 |
